FOUNTAIN PENCIL.

Application filed June 26, 1922.

To all whom t may concer/fi I Be it known that I, EDWARD C. BERNERS, acitizen of the United States, and resident of Two Rivers, in the countyof Manitowoc and State of Wisconsin, have invented certain new anduseful Improvements in Fountain Pencils; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention refers to fountain pencils for the distribution of fluids,such as glue, or the like. Y f

The primary object of my invent-ion is to simplify the construction ofsuch pencils, whereby the lling opening in the hollow stem thereof isdispensed with and the dis-v tributing end of the pencil is utilized forboth filling and distribution of the fluid.

Another object of my invention is to provide a sleeve for closing thedistributing end A of the pencil, which sleeve carries various types ofdistributing nozzles to be selectively used.

Another object of my invention is to provide the closure sleeve withexteriorly tapered walls having a resilient surface thereon forengagement with the lip of the stem distributing opening, said openingback of the lip being provided with an eX- pansion chamber or cavity,whereby the sleeve, which is in the form of a cork, will be rmly heldagainst displacement when the pencil is in use to thus prevent leakage.

Another object of my invention is to provide a. hollow pencil stemhaving a closed end, and an open distributing and filling end, the lipsabout the open end being merged into an expansion chamber back of thestem, whereby a slight cavity is formed between the sleeve or core andthe juxtaposed walls of the filling end to produce a Suction chamber,thereby preventing accidental discharge of the cork.

Another object of my invention is to provide the cork or closure sleevewith various forms of distributing nozzles to meet the requirements ofthe trade.

A further Objectis to provide the hollow stem with correspondingdiameter shouldered collars at its ends for selective engagement with athimble, which thimble can be nested over the filling opening parts,when the pencil is not in use, to protect the same, and it can beadjusted over the closed end of the stem to lengthen said stem when theinstrument is in use.

Seria No. 571,102.

Another object of my invention is to form the hollow stem of the pencilfrom such sub stance as hard rubber, whereby accuracy is obtained andthe life of the stem body is thus increased.

Vith the above and other minor objects in view, the invention consist-sin certain peculiarities of construction and combina tion of parts, asare hereinafter set forth with reference to the accompanying drawingsand subsequently claimed.

In the drawings Figure l is a sectional elevation of a fountain pencilembodying the features of my invention, the same being shown equippedwith a closure sleeve and mucilage distributing nipple, which nippleforms the nozzle part that is associated with the sleeve.

Figure 2 represents a fragmentary view of the pencil stem and closuretherefor, the closure being formed integral with a pointed nozzlehavinga flexible air dome as sociated therewith, and

Figure 3 is a similar sectional view showin@ the distributing end of thepencil equipped with a porous nozzle in conjunction with the closuresleeve, whereby fluids, such'as water, can be distributed from thepencil body.

Referring by characters to the drawings, l represents a hollow body orstem, preferably formed from one piece of hard rubber', having a closedend 2 and an open distributing and lilling end 3. The ends of the pencilare formed with 'shouldered collars 4-4, which collars are of the samediameter andadapted to selectively receive a thimble 5 that is adjustedin position to close the discharge end of the pencil or add length tothe rear closing endthereof, the same being frictionally held.

The hollow body of the stem l is of slightly greater diameter than theunder discharge end bore l and the discharge end.

bore rearward of the mouth lips 3." is expanded slightly to form achamber 6.: The distributing mouth of the stem is closed by a stopper,preferably in the form of ay `sleeve 7, which sleeve may be composed ofhard rubber, or other fibrous material, and

the outer wall of the stem is tapered inwardly and fitted with jacket 8,which jacket is expanded over an annular end bead 7, whereby it is moresecurely locked in position with relation to the tapered surface of thesleeve.

a soft rubber Asshown in Figure l of the drawings, the outer end of themembraneous jacket 8 is continued to form a pliable distributing nozzle9, the end of which is formed with suitable apertures, whereby fluidcontained in the stem will be discharged in the desired volume by theoperator when pressure is put upon said nozzle.

Referring. to Figure 2 of the drawings, the'body of the stopper orsleeve 7 is continued" outwardly to form a rigid pointed nozzle 9',which nozzle, when not in use, is closed by a metallic pin 10 to thusprevent clogging or gumming up of the mouth of thenozzle'by the fluidwhen it is not in use. Thisform of'nozzle is particularly used byphotographers or artists and it is formed w'tlil a rearwardly extendedhollow neck 1l, to whichV neck isfitted a closed rubber nipple l2constituting a flexible air dome.

When this form of nozzle is inruse, the operator, inv manipulating thepencil, can, by; ,pressure` of the flexible air dome or nippleereateaforced'draft through the nozzle,

Wheleby,A a positive spray is discharged` therefrom, the nipple in itsfunctioning being 'contracted and expanded alternately and` this actioncan be effected by a pressure offene. finger thereupon, so as not tointerfere` with'proper manipulation of the pencil.

Referring now to Figure 3 of the draw- Vingsg the sleeve 7 is providedwith a soft rubber jacket similar to that shown inconnection'with theother formsy ofA my inventi'on, except' inV this case the discharge endo fjth'ejacket is contracted over the beaded endt'f ofv the sleeve toform a restricted dischargeiopening m, which opening is fitted withasponge or other porous substance y, whereby fluid contained' in the bodyof the penciltcanbe distributed, as for example, in somecases thepencil) may be used forwater on other fluid and. canlbe used for thepurpose of aflixingstamps, or moistening any gurnmedf' surface.

' lt'.l will be noted from the foregoing that inweach instance theremovable nozzle, which forms a closure or cork for the opendisclarge'end offthesame, is provided with a tapered exterior wallcovered by the flexible jacket: Iti is to be noted that the hollowharrell isiprovided with aslightlytapered portion adaptedto receive theinner end of the; stopper and is provided withv an expandedy portion 3in front of such tapered portion. Thereafter, this expanded portioncontracts and forms a relatively inturnedlip which-` also forms acontracting ring like member adapted to gripy the stopper or itsmembranous jacket and thus secures a firm holdl thereon;

Heretoforethis closure problem has confronted'I all manufacturers ofdevices of this character and my present invention has solved thelproblem of' a secure closure,

whereby economy in manufacture is insured and whereby the pencil stemcan be formed with a single opening, whereas, under ordinary conditions,itwas necessary to form the stem having both ends open, one of which wasfor the purpose of filling and necessarily to be corked with means forremoval, rendering a liability of the corked end to become disarrangedunder ordinary office usage.

In practice, the pencil is sold with. the combination stopper, asdisclosed, and sold to the trade with an extra stopper,such as shown' inFigure l of the drawings. The rubber tit or nipple of the stopper, underordinary usage, sometimes becomes gummed up by a surplus of glue ormucilage. ln this case, the gummed stopper is removed quickly and can becleansed by soaking it in water, which soaking will remove all thesurplus glue and soften the rubber to thereby add life to it. l/Vhen thegummed stopper is in the process of cleaning/by soaking, theextrastopper supplied with the pencil is tem-- porarily used and is insertedin the mouth of the hollow stem for immediate use. The extra stopper canthen be used indefinitely andr thereafter it can be replacedr by thecleansed stopper, which had previously been put into soak for renewalpurposes.-

While l have shown and described a simple exeinplification of myinvention ini nutely with reference to all of its details, it isunderstood that the shapes of the various parts and minor details ofconstructionmay be varied within the scope of the kappended claims.

IV claim l. A fountain pencil comprising a one.

piece hollow stem having a single openingV therein, saidv opening-beingfor-med by a contracted portion and' having an enlarged Vportionimmediately in front' of said contracting portion, said-enlargedVportion terminating in an inturned edge, a closure having an aperturetherethrough, a membranous jacket surrounding said closure and wedgedbetween 'said closure and the'- contracted part and inturned lip.

2. A fountain pencil comprising a hollow barrel closed at one end andhaving an opening at the other end, a discharge member-v fitted withinsaid opening and having a passageway therethrough gradually contracting`towards its outer end, said discharge member having a laterally offsetneck provided with a passageway communicating withsaid first mentionedpassageway, and a flexible bulb connected lwith said neck. v Y

In testimony thatl claim the foregoingv I have hereunto set my hand atTwo Rivers. in the county of Manitowoc and Statek ofil Wisconsin. v
